frida框架hook常用字符串模板總結

ArrayBuffer轉String: 解決中文亂碼(模板)

function ab2str(buf) {
    return new Uint16Array(buf)
    // encodedString = String.fromCodePoint.apply(null, new Uint16Array(buf));
    // // decodedString = encodeURI(encodedString);//沒有這一步中文會亂碼
    // // console.log(decodedString);
    // return encodedString
}

string轉ArrayBuffer(模板)

function str2ab(str) {
    var buf = new ArrayBuffer(str.length * 2); // 每個字符占用2個字節
    var bufView = new Uint16Array(buf);
    for (var i = 0, strLen = str.length; i < strLen; i++) {
        bufView[i] = str.charCodeAt(i);
    }
    return buf;
}

字符串轉Uint8Array(模板)

function stringToUint8Array(str){
  var arr = [];
  for (var i = 0, j = str.length; i < j; ++i) {
    arr.push(str.charCodeAt(i));
  }

  var tmpUint8Array = new Uint8Array(arr);
  return tmpUint8Array
}

Uint8Array轉字符串(模板)

function Uint8ArrayToString(fileData){
    console.log(fileData)
  var dataString = "";
  for (var i = 0; i < fileData.length; i++) {
    dataString += String.fromCharCode(fileData[i]);
  }

  return dataString
}
